Numeric keypad

With the Num Lock key you can manually switch on or off the numeric keypad on your keyboard. Also, computers' BIOS settings often include an option to decide if the computer should be started with the numeric keypad enabled. Otherwise, this is a way to configure it:

  1. Install the numlockx package.

  2. Open Startup Applications and add a startup program with the command: numlockx on

If you want the numeric keyboard to be on also at the login screen, you can create a special configuration file. Press Ctrl+Alt+T to open a terminal window, and then run this command (it's one long command, even if it may be shown wrapped on the screen - copy and paste to get it right):

sudo sh -c 'printf "[SeatDefaults]\ngreeter-setup-script=numlockx on\n" >/usr/share/lightdm/lightdm.conf.d/50-numlock.conf'
